Appendix II I/O Daughter-card Options
ADAT Optical I/O
The ADAT Optical daughter card offers 16 channels of audio input and 16 channels of audio output, 8
channels per optical connection. From top to bottom of the card, it has two digital optical input connec-
tors (Inputs A and B) and two digital optical output connectors (Outputs A and B).
The signal format of optical connectors Input A and Output A can be set inside the Pyramix software to
operate in either ADAT or S/PDIF mode. When in ADAT mode, there are 8 discrete audio channels car-
ried per each optical connector. S/PDIF mode has 2 channels per optical connector.
Note: in SPDIF mode the maximum sampling rate is limited to 48 kHz
AES/EBU I/O
The AES/EBU daughter card offers 24 channels of I/O over 12 AES/EBU input and output pairs. Con-
nection is via three DB-25 connectors, One on the main card attached to the Mykerinos and two more
on a separate bracket connected via internal ribbon cable to the main card. An optional break-out cable
can be ordered separately which connects to the DB-25 connector and terminates in 8 XLR connectors
which may be used to connect to standard AES/EBU stereo inputs and outputs. AES daughter cards
are available with or without 8 channels of SRC (sample rate conversion)
Dual DC I/O
The Dual DC offers up to 12 inputs and outputs at 32kHz, 44.1kHz or 48kHz sampling rates on a single
board. All converters are 24 bit. Connection is via 2 DB-25 connectors. One, on the main card attached
to the Mykerinos, carries the analog I/O and the second, on a separate bracket, carries four AES/EBU
Input and Output stereo pairs. There are four analogue Line outputs and four analogue Line Inputs, two
of which may be switched to accept Mic or Line level inputs. These have Mic pre-amps and 48V phan-
tom powering. The analogue Line level I/O is adjustable over a 24dB range to accommodate all stan-
dard studio levels. Optional break-out cables can be ordered separately which connect to the DB-25
connectors and terminate in 8 XLR connectors.
The Dual DC is the most cost-effective I/O daughter card for Pyramix users. It is an ideal I/O solution for
mixed analog/digital requirements, as encountered in Broadcast production, and Video post-production
environments. It allows direct connection of up to two dynamic or condenser microphones, typically for
quick and easy voice-over recording.
Note: the Dual DC I/O daughtercard is not HDTDM bus compatible and can not be
used in a multiboard setup.
MADI I/O
The MADI daughter card offers 56 channels of 24 bit bi-directional I/O, and up to 64 channels in MADI-
X (MADI Extended) format. It can be ordered either in a BNC coaxial version or an optical duplex SC
version. Both versions are fitted with a standard Wordclock BNC I/O connector, which can be pro-
grammed in the Pyramix software as a Wordclock In or Out signal.
SDIF I/O
The Mykerinos SDIF daughter board is specially designed for multi-track DSD recording. It offers 8
channels of DSD digital input over 8 unbalanced, 75 Ohm terminated BNC connectors and 8 channels
of DSD digital output over 8 unbalanced, 75 Ohm BNC connectors.One channel of DSD signal is trans-
ported at the bit-rate of 2.82 MHz through each BNC connector. SDIF-2 and SDIF-3 format are fully
supported for DSD transport (selected under software control)
